can i launch a new coroutine inside a suspending function with the same scope the suspending function was called ? sth like this
Copy code
suspend fun test() {
   suspendingFunctionScope.launch {
      ...
   }
}

You can make test an extension function on a coroutineContext
t
Yes, you can wrap your
launch
call into a
coroutineScope
block:
Copy code
suspend fun test() = coroutineScope {
    launch {
        ...
    }
}
Note that the
test
function will not return before the launched coroutine is completed. If that's not what you want, you should consider making
test
a non-suspending extension of
CoroutineScope
, which is the usual way to define a function that starts a coroutine:
Copy code
fun CoroutineScope.test()
a
is it possible to have this somehow object oriented like this ?
Copy code
class GameEngine {
    fun CoroutineScope.start() {
...
}
t
You can do that, but it's not very handy. You would have to write something like this:
Copy code
val engine = GameEngine()
with(engine) {
    scope.start()
}
This is because a member function can (normally) have only one receiver. Something like
Copy code
fun startIn(scope: CoroutineScope)
would be better. You can also pass a
CoroutineScope
as a constructor parameter of your engine, provided the engine has the same lifetime as the passed scope.

thank you now its clear to me ­čĹŹ
